I've used for quite some time now a combination of
postfix+SA+MailScanner for this, not delivering mails, but letting those
in a quarantine, and using Mailwatch (http frontend) to let people
release mail from the quarantine, etc ..

https://www.mailscanner.info/
https://mailwatch.org/

And the ansible role that I initially used for this on CentOS 7 :
